To determine if 7212 is a prime number or a composite number, we simply look at the factors for 7212.
If the factors of 7212 are only 7212 and 1, then we know that 7212 is a prime number. Otherwise, 7212 is a composite number.
To explain better, if 7212 is only divisible by 1 and 7212, then it is a prime number, and if 7212 is divisible by more than 7212 and 1, then it is a composite number.
The factors of 7212 are as follows:
1, 2, 3, 4, 6, 12, 601, 1202, 1803, 2404, 3606, 7212
Therefore, since 7212 is divisible by more than one and itself, the answer to the
question "Is 7212 prime or composite?" is highlighted in blue below.
composite
Is 7213 prime or composite?
